Many people don’t realise dark mode is an accessibility feature. It’s often just considered a nice to have, a cool extra feature that power users will love. But dark mode is also a valuable accessibility feature. Some types of visual impairment can make it painful to look at bright colours, or large blocks of white might wash over the black text. Some people with dyslexia or Irlen’s Syndrome can struggle to read black text on a white background. Like almost any accessibility feature, dark mode is about providing flexibility to your users so they can use your app in the way that is most comfortable to them.
